Ladies, can you tell me if anyone has experienced something similar? I have pimples that constantly migrate. At first they cluster on my forehead, and the rest of my face is clean. They stay there for a while, then they affect my cheeks, and the forehead becomes clean again. Now they're all over my chin. I naturally try to take care of my skin, cleanse it, moisturize it, but still, in some area of my face, there will be a bunch of pimples, and this has been going on for about 4-5 years. If it were acne everywhere, I would understand, but this "migration" I don't know how to explain.
